Hi,

I'm going to design a continuous time comparator using non-compensated op amp. So, how to implemented hysteresis for this comparator. Remember the op amp itself will have some offset. Thanks!
 

1)Use small current sources in parallel with diff. pairs load. Switch between them thought MOS switches in dependence of output state.
2) Another kind of circuit u can see at the attached picture
 

Yes , DenisMark's ideas is good. The first one is so easy to finished.
You can set the size ratio of the M3 to M10 to set the hysteresis.Please refer the Allen' s book for the more information.
